Abstract

The invention discloses a compound spinning component used for a melt-spinning device, and the compound spinning component can spin N plus N segments (6 plus 6 segments-64 plus 64 segments, and the like) of orange segment-shaped staple fiber. The compound spinning component is composed of a feed plate, a sealing plate, a filter mesh, three distributing plates and a spinneret plate from top to bottom. A and B groups of melts enter melt flow channels which are 2-10 in total and distributed evenly of the two groups from the upper part of the feed plate and are jetted by the spinneret plate after passing through the sealing plate, the filter mesh and the three distributing plates. The compound spinning component is shaped like a rectangle for facilitating the pumping of monomers in the spinning process; the compound spinning component is applicable to the spinning of PET and PA6, PET and PP, PET and PE, PE and PA6; as the special flow channels fully mix the melts, jetted tows have uniform size and stable quality; the technical proposal has universality and can be popularized and applied in sheath-core type, sea-island type and other peel-off type composite spinning components.

Description

Composite spining module

Technical field

The present invention relates to a kind of composite spining module that is used on the apparatus for melt spinning, particularly two kinds of different high polymer moltens are processed into the filament spinning component of composite fibre, belong to the synthetic fiber production technical field.

Background technology

Composite fibre is meant by two or more high polymer, or has the chemical fibre that the same high polymer of different molecular weight is made through composite spinning method.Two kinds of melts by two extruders system enter in the composite component of composite spinning case via different melt canals respectively, at the suitable position of spinnerets with certain complex method with together, from a spinneret orifice extrusion molding, again through cooling, oil and processing technology such as coiling and make 0.1dtex～0.3dtex even thinner superfine fibre.Superfine fibre is widely used in fabrics such as dermatine, artificial suede, clean-cloth, fast dry towel at present, but only develops tangerine lobe type long filament composite spining module at present, and the still untapped success of tangerine lobe type short silk composite spining module.
